Electrical power is generated by a single bearing, synchronous, brushless, self-ventilated gen-erator assembly with an integral exciter assembly. Unit maintenance of the generator assembly is limited to visualinspection of the generator and the generator bearing.4-83UNITMAINTENANCEINSPECTIONOFGENERATORASSEMBLYa.Visually inspect generator assembly for insecure mounting, cracks, corrosion, accumulations of foreignmaterial in ventilator screens and other damage.b. Listen for unusual noises while operating.c.Notify higher level maintenance of any discrepancies found during inspection.Section XVII. UNIT MAINTENANCE OF THE HOUSING AND SKID BASE ASSEMBLIES4-84 GENERAL. The housing assembly fully encloses the top, sides and ends of the generator set. It consistsof doors, covers, and panels. The cooling air intake openings which provide access to internal components are cov-ered by doors which are equipped with seals to prevent the entry of foreign materials when the doors are dosed.The cooling air exhaust opening is covered by the shutter and grille assemblies (paragraphs 4-36 and 4-37). Theplate and sleeve assembly allows connection of load lines while excluding foreign materials. The lifting frame, lo-cated in the center of the housing assembly, is equipped with lifting clevises at the top of each side to which a hoist-ing sling may be attached. The housing assembly is supported on the skid base assembly which also provides sup-port for the engine and generator assemblies. The skid base also provides the generator set grounding point andis drilled to accept attachment of the wheel mounting kit and M-200 trailer. A metal sheet near the bottom of theskid base prevents the entry of debris. Drain holes prevent the accumulation of spilled liquids on the sheet.4-85 DOORS, COVERS, AND PANELS.NOTEIt is not necessary to completely disassemble the housing assembly.
